HARROW nrrncnmnnr non rnows.

Application filed july 11,1925. Serial No. 42,963.

To all whom it may concern:

Be it known that I, RALrrr A. DANSKIN, a citizen of the United States, residing at Beaver Crossing, in the county of Seward, State of Nebraska, have invented certain new and useful Improvements in Harrow Attachments for Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in plows, and particularly to harrow attachments therefor.

One object of the invention is to provide a device of this character which may be readily attached to the ordinary plow, without modifications thereto.

Another object is to provide a harrow attachment for a plow, which is arranged to yield, when passing over large clods, or stones, whereby to prevent breakage of the device.

'Another object is to provide an attach ment of this character which is readily adjustable to suit various conditions of use.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying Figure 3 is an enlarged vertical longitudinal sectional v1ew on the line 3-3 of Figure 2.

Figure 4 is an enlarged section on the line 4t of Figure 2.

Referring particularly to the accompanying drawing, represents the moldboard, and 11 a portion of the beam of a plow, in connection with which the present, invention is particularly adapted for use.

Properly bolted to the lower portion of the beam 11, adjacent the landside 12, of the plow, is the shorter arm 13 of the L-shaped member 13, the outer end portion of the other arm of which is provided with a pair of longitudinally spaced openings which receivethe bolts 14: and 15, respectively. Secured to the rear face of the moldboard, and inclined upwardly and outwardly therefrom, is a bar 16, a bolt 17 being disposed through the moldboard and through a longitudinal slot 18, formed in said bar, whereby said bar is capable of limited slidable adjustment on the moldboard. The lower end ,of the bar 16 is flared, as at 19, and formed in this portion is a transverse slot 20, while a single circular hole 21 is formed in'the' bar intermediate the slot 20 and the slot 18. The bolts 1a and 15are disposed respectively through the lower and upper openings of the L- shaped member, and through the slot and hole'21, whereby the bar 16 is capable of swinging or pivotal movement on the bolt which secures the bar to the moldboard. and represented at 17, to dispose the bar at different angles with respect to the moldboard. The slot 20 is preferably arcuate, and is concentric with the opening through which the bolt 17 passes. Nuts on the various bolts permit clamping the parts, in adjusted positions. The upper end of the bar 16 is bent to extend downwardly and rearwardly, as shown at 23, and the extremity of this portion 23 is rolled into tubular form, as shown at 24 to receive a pivot member 25 therethrough. In the portion 23, rearwardly of the bend, there is formed an opening 26 which receives the lower end of a bolt 27.

Disposed above the portion 23, and extending downwardly and rearwardly, is a bar 28, the upper end of which is formed with an opening receiving the upper end of the bolt 27, a nut 29 being engaged on the bolt above the bar 28, and a coil spring 30 being disposed on the bolt, between the bar 28 and the portion 23. Struck out from opposite sides of the bar 28, intermediate the length thereof, are the downwardly extending apertured cars 31, which receive the ends of the pivot member 25. The lower end of the bar 28 is formed with an angularly extending foot 32, and has a lower corrugated face and a vertical opening for the reception of the bolt 33. A metal strap 34: is secured to the foot 32, by means of the bolt 33, and has its upper face corrugated for meshing engagement with the corrugations of the foot, whereby to permit rotary adjustment of the strap with rela tion to the foot. The opposite ends of the strap are rolled into tubular form, as shown at 35, and embrace the intermediate portions of the tubular harrow tooth supporting bars 36. Screws 37 are engaged through these tubular portions to bite into the bars 36, whereby to permit rotary adjustment of the bars within the portions 35, for the purpose of setting the harrow teeth at different angles with relation to the ground.

Engaged through an opening in the bar 28, forwardly of the pivot end thereof, is

an end of a brace rod 88, the other end of which is properly secured to the lower end of the beam 11.

By the above construction, and arrangement of parts, the harrow may be adjusted vertically, as well as laterally, with respect to the plow, whereby to act upon the soil according to the desires of the user, and the conditions of the crops, or soil.

Vhatis claimed is:

A harrow attachment for a plow comprising a bar adapted for slidable and pivotal adjustment on the moldboard of a plow and arranged to extend laterally therefrom, the outer end of the bar being rearwardly and downwardly directed, and having a terminal eye carrying a pivot member, a lever extending longitudinally of the rear- Wardly directed portion of the bar and having'a pair of depending ears straddling said eye and receiving said pivot member for vertical movement, a harrow carried by the rear end of the lever, a terminally headed bolt disposed through the forward end of said lever and the forward end of said rearwardly directed portion of the bar, and a spring on said belt for rocking the lever to yieldably maintain the harrow in'grounri engaging position. i

In testimony whereof, I affix my signature.
